Marine Fresh Water Hand Pump

I. Product Overview

The marine Hand fresh water pump is a core emergency equipment of the ship's fresh water transportation system and can also serve as an auxiliary water supply device. It is specially designed for fresh water transportation in emergency scenarios such as power outages and equipment failures. Its core working principle is to drive the internal gear or piston movement by manually rotating the rocker arm to form negative pressure suction, realizing the suction, pressure boosting and transportation of fresh water. Relying on corrosion-resistant materials and a compact structure, it is suitable for the complex marine environment with high salt spray and high humidity, and can stably transport media such as domestic fresh water and clean fresh water. The product strictly complies with standards such as the International Convention for the Safety of Life at Sea (SOLAS) and GB/T 10832-2011 *Marine Pumps*, has obtained certifications from mainstream classification societies such as CCS and ABS, and is widely used in various ocean-going, coastal and inland river ships. It is an essential equipment to ensure the emergency fresh water supply of ships.

II. Core Parameters 

III. Core Advantages

Power-Free Emergency Guarantee: Purely manual drive, no need for external energy such as electricity or fuel oil. It can be quickly started in case of power outage or equipment failure to ensure uninterrupted emergency fresh water supply.

Strong Corrosion Resistance and Adaptability: Adopts corrosion-resistant materials and enhanced sealing design, which can effectively resist the erosion of high salt spray and high humidity environment on ships, not easy to rust and scale, and has a long service life.

Simple and Reliable Structure: Few core components, low failure rate, no complex daily maintenance; Small in size, flexible in installation, and suitable for installation in narrow spaces of ships.

Convenient and Efficient Operation: Humanized rocker arm design, which can be easily operated by a single person. The speed is controllable, and the fresh water delivery volume can be adjusted according to needs; No preheating required for startup, with rapid response.

IV. Typical Application Scenarios

Ship Emergency Fresh Water Supply: Provides drinking water and emergency clean fresh water for crew when the main power supply fails or the main fresh water pump is damaged.

Deck/Cabin Cleaning: Serves as an auxiliary equipment to transport fresh water for deck flushing and mild cabin cleaning.

Engine Room Emergency Drainage: Can be temporarily used for draining a small amount of fresh water accumulation in the engine room to avoid water accumulation affecting equipment operation.

Daily Water Supply for Small Ships: Suitable for small inland river ships, fishing boats under 500 tons, etc., as the main equipment for daily fresh water transportation.

V. Selection and Precautions

1. Selection Basis: Determine the flow demand according to the ship's tonnage (number of crew members). For ocean-going ships, stainless steel materials are preferred to enhance corrosion resistance; for small inland river ships, cast iron materials can be selected; Determine the pump body size according to the installation space.

2. Daily Maintenance: Regularly check the integrity of seals to avoid fresh water leakage; Rotate the rocker arm monthly to lubricate transmission components and prevent jamming; Regularly clean the inlet filter screen to avoid impurity blockage affecting transportation efficiency; Flush the pump body with clean water and store it in a dry place before long-term shutdown.

3. Operation Specifications: Check the status of inlet and outlet valves before startup to ensure unobstructed pipelines; Rotate at a constant speed during hand cranking to avoid component wear caused by excessive speed; Close the inlet and outlet valves after transportation and empty the residual fresh water in the pump body.

4. Compliance Requirements: Select products with classification society certifications (such as CCS/ABS) to ensure compliance with ship emergency equipment safety standards.
